Q: Check engine light stays on. on 2007 Buick Lucerne

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
We recently purchases a 2007 Buick Lucerne. After getting gas, the message for fixing the gas cap came on. My husband tightened the gas cap and then the check engine light came on and has stayed on for the last 2 weeks. We took the car back to the dealer and they said they found nothing wrong and yet the check engine light stays on. We got the service record from the previous owner and they had taken the car back to the dealer about 4 or 5 times just before they traded the car in. What is causing the check engine light to come on? We are taking the car back to the dealer this week. At what point do we determine that we have a lemon? We really do like the car, but not if we have to pay for repairs that appear to go back to before we owned it.

random thought i had a similar issue with a gas cap try a new one from a parts store for your car, the light comes on for a leak from the evap system and once I changed it everything worked fine
